Some Ajax tips & tricks

Display an hourglass

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);
function InitializeRequest(sender, args) {
document.body.style.cursor = "wait";
}
function EndRequest(sender, args) {
document.body.style.cursor = "default";
}

Click-once button control

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);

var btn;

function InitializeRequest(sender, args)
{
document.body.style.cursor = "wait";
var btnId=args._postBackElement.id;
btn= document.getElementById(btnId);
if (btn.type=="button" || btn.type=="submit")
btn.disabled=true;
}

function EndRequest(sender, args)
{
document.body.style.cursor = "default";
if(btn!=null) btn.disabled=false;
}

Code explanation:

In the InitializeRequest function we retrieve the pressed button id, by retrieving the _postBackElement which is passed as an argument, and after we verify if it is a button. We must declare the button variable as a global variable, to allow the EndRequest function to know which button fires the event.
Note that the above function will work ONLY if the button control is inside an UpdatePanel. And that's it! We have a click-once button! We can even put it in a MasterPage to propagate behavior to your content pages...

HIT MAN
